Specification of Letters Patent.

Patented Jan. '7, 1908.

Application filed June 14, 1907. Serial No. 379.054.

To all whom it may concern:

Be it known that I, GILBERT, W. Goon- RIDGE, a citizen of the United-States of America, residing. at Bridgeport in the county of Fairfield, in the State of Connecticut,,have invented a certain new and Improved Receptaclefor Incandescent Lamps, of which the following is a specification.

My invention relates more particularly to that class of receptacles for electric incandescent lamps which are commonly termed sign receptacles, that is, receptacles for use in electric advertising signs.

The object of my invention is to provide an improved receptacle for this use, which will be stronger and less liable to breakage than the present porcelain sign receptacle, and which can be quickly and easily applied.

In theaccompanying drawings Figure 1 is a sectional view of my improved receptacle on the line 11, Figs. 3 and 5; Fig. 2 is a side elevation corresponding with Fig. 1; Fig: 3 is another side elevation, the receptacle being turned one quarter round from the position Fig. 2; Fig. 4 is a perspective view; and Fig. 5 is an inverted lan. My receptacle comprises a ody part A hollowed to contain the usual lam -receiv ing terminals 6 and 7, and open at t e front.

Near the open front end of the receptacle are ;outside lateral lugs 8 and 9 by which the re ceptacle may be secured to the rear of the metallic si n plate S, by screws 3, Fig. 1. In order to acllitate the labor of attaching these receptacles, and to dispense with the use of the loose nuts commonly used, I socure permanently in holes in the porcelain lugs threaded bushings 10, as by flangmg the ends of the bushings, as shown in Fig. 1.

At the rear of the receptacle I provide lateral lugs 11, 12, which are diametrically opposite each other and preferably in a plane at right angles to a plane passing centrally through the open lugs 8, 9. These lugs 11, 12 are notched at the rear for the passage of the line wires, bared portions of which are secured under bindingscrews 13 on terminal plates 14, 15 connected in any suitable manner, to the lamp receiving terminals within the receptacles.

I form the receptacle with its lugs of porcelain or other such insulating material, and in order to lessen liability of the breaking off of any of the lugs 8, 9, 11, 12, I connect those at the front of the receptacle with those at the back by curved flanges 16.

I claim as my invention 1. A sign receptacle having laterally projecting lugs at front and back with connecting strengthening ribs.

2. A sign receptacle having a pair of diametrically opposite lugs at the front and a.
